3.1 Control/Sense Commands

(1)Paramter code

This field identifies the log paramter being transferred for that log page.

(2)Byte 2

a)DU (Disable Update)

"1" : The IDD does not update the log parameter value except in responce to a LOG SELECT command that specifies a new value for the parameter.

"0" : The IDD updates the log parameter value to reflect all events that are noted by that parameter.

b)DS (Disable Save)

"1" : The IDD does not support saving that log parameter in response to LOG SELECT or LOG SENSE command with an "SP" bit of one.

"0" : The IDD supports saving for that log paramter. The IDD saves the current parameter value in response to LOG SELECT or LOG SENSE command with a "SP" bit of one.

c)TSD (Target Save Disable)

The IDD does not support this bit. For LOG SENSE command (See 3.1.17), the IDD always report zero. Also, for this command, the IDD accepts this bit value of "1", but ignores its functionality.

d)ETC (Enable Threshold Comparison)

The IDD does not support this bit. For LOG SENSE command (See 3.1.17), the IDD always report zero. Also, for this command, the IDD accepts this bit value of "1", but ignores its functionality.

e)TMC (Threshold Met Criteria)

This field is ignored when "ETC" bit is 0. For LOG SELECT command (See 3.1.17), the IDD accepts this field value of other than "00b", but ignores its functionality.

f)LBIN

This bit is only valid if the "LP" bit is one. If the "LP" bit is one and this bit is zero then the list parameter is a string of ASCII graphic codes.

If the "LP" bit is one and this bit is one then the list parameter is a list of binary information.

g)LP (List Parameter)

"1" : The parameter is a data counter.

"0" : The parameter is a list parameter.

If these bits are specified by LOG SELECT command, the IDD terminates normally. But the IDD's action is not changed.

For LOG SENSE command, these bits always report value defined in each log page (see 4.2).

(3)Parameter length

This field specifies the length in bytes of the following parameter value. If the application client sends a parameter length value that results in the truncation of the parameter value, the device server terminates the command with CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00]).
